I also took a measurement from a always exposed portion of the rear subframe for future reference.

2021 718 GT4

245/35ZR-20 CONTINENTAL EXTREMECONTACT DWS 06 PLUS XL @ 30.5 psi

295/30ZR-20 CONTINENTAL EXTREMECONTACT DWS 06 PLUS XL @ 32 psi

Front ride height - 93mm (LOLOLOLOL)
Rear ride height 104mm (left) 105mm (right). I think I measured from the wrong spot on the subframe, how could it be 26mm below factory spec?

Fender ride heights
664mm Front Left (26" 1/8), 667mm Front Right (26" 1/4)
676mm Rear Left (26" 5/8), 679mm Right Rear (26" 3/4)

(my metric to inch conversion is for convenience, actual conversion should be in 64th of inch)Pictured is the rear ride height location I "added" since the subframe is usually covered. This distance to ground is 86mm (left) and 88mm (right). I realize these numbers are meaningless to others without knowing the tire height. Welp, thats life.


If my rear subframe measurement was actually from the right spot, I'll probably raise the rear for more rake. Hopefully I just measured wrong.
